# Tendon Stressing \[SIG]

## Tendon Stressing

For additional loads that arise due to using Tendons for structural elements can be calculated and defined using this object.

**Stage:** This parameter can be used to specify the stage at which the load is initially applied to the structure.

**Tendon:** Selecting the modeled tendon that will be used for load calculations is done by specifying this parameter.

**Stressing At Start(%):** Jacking force at the start point of the tendon.

**Stressing At End(%):** Jacking force at the end point of the tendon.

**Instantaneous Elastic Shortening Loss \[Ignore/Include]:** The immediate loss of prestressing force in the tendons due to the elastic shortening of the concrete upon the application of the prestressing force can be defined using this parameter.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openbrim.org/templates/steel-i-girder-bridge-workflow/loading-sig/loads-sig/prestressing-load-sig/tendon-stressing-sig.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
